U.F.O. Sighting Report — Winnetka, Illinois, 26 July 1965

This document is a formal U.F.O. sighting report filed by the 928th Troop Carrier Group (Reserve) of the United States Air Force, based at O'Hare International Airport in Chicago, Illinois. The report details an incident occurring on 26 July 1965 at 0230Z in Winnetka, Illinois. The witness, a 37-year-old civilian systems analyst, observed a single, round, blue-white object that appeared to be reflecting light. The object was described as being the size of a pinhead at arm's length. It maintained a steady light for approximately 20 degrees of an arc, faded for about 1.5 seconds, and then reappeared. The object followed a straight path due south, moving from an initial observation point 45 degrees above the horizon in the north to a disappearance point 30 degrees above the horizon in the south. The total duration of the sighting was two minutes. The weather conditions were reported as clear with unlimited visibility. The observer noted that the object's angular motion was much greater than that of the ECHO satellite, though it was not as fast as a meteorite hitting the atmosphere. Clayton W. Salmonson, a Base Flight Operations Dispatcher, reviewed the report and expressed high regard for the witness's integrity. While Salmonson stated he had no definitive explanation, he concluded that the object was likely a satellite, possibly the ECHO satellite, based on its flight characteristics.
